Ferrous metals contain iron, non-ferrous metals generally do not. For instance, non-ferrous metals include aluminum, copper, brass, bronze, and nickel. From there, the metals are further defined by the alloying elements, so it’s important to keep in mind what the general chemistry does to both ferrous and non-ferrous metals.
Alloy steel is a metal consisting mainly of iron but which includes small amounts of other elements such as: carbon, chromium, manganese, molybdenum, nickel, silicon, tungsten, or vanadium. These elements are added to alter the physical properties of the steel to improve such things as hardness, strength, or corrosion resistance.
Alloys containing 72-83% nickel have the best soft magnetic properties and are used in transformers, inductors, magnetic amplifiers, magnetic shields and memory storage devices. Nickel-Copper Alloys. These are highly resistant to corrosion by alkaline solutions, non-oxidizing salts and seawater. The best-known is Alloy 400. Nickel-Molybdenum Alloys
And while there are steels that have up to 2 percent carbon content, they are the exception. Most steel contains less than 0.35 percent carbon. To put this in perspective, keep in mind that's 35/100 of 1 percent. Now, any steel in the 0.35 to 1.86 percent carbon content range can be hardened using a heat-quench-temper cycle.
Nickel allergy is a type of allergic contact dermatitis. A nickel allergy is commonly encountered with jewelry, kitchen tools, and silverware. In individuals who are sensitive to nickel, ingestions of certain foods (e.g., chocolate, nuts, oats, green beans, peas) may cause systemic nickel allergy syndrome (SNAS) or lead to chronic dermatitis.

In the United States, the leading uses for primary nickel are stainless and alloy steels, nonferrous alloys and superalloys, electroplating, and other uses including catalysts and chemicals. Domestic production of stainless steel was estimated to have decreased by approximately 10% in 2019. Consumption of nickel used in alloys for jet turbine
